Who Did That? a Trail of Tracks and Traces Who Did That? A trail of tracks and traces Alive with discovery Welcome! The Who Did That? trail introduces children to concepts such as adaptations for survival, animal architecture, biodiversity and pollination – and that plants hold the key to animal diversity. • Take your time to explore. • Carers may need to read the booklet to younger children and explain some of the words used. • Look up and around to discover all of the creatures lurking about. • Some activities in this booklet are designed to be completed at home after your visit. Along the way keep an eye out for... A Tasmanian Devil A Sleepy Wombat A Green and Golden Bell Frog A wild bush shelter How many Fairy Wrens can you spot? Blue Fairy Wren 2 The buzz about bees There are over 2000 different species of native bees in Australia. Look closely and you might spot Betty the Bee along the trail. Many native bees are solitary and do not sting, unlike the introduced Honey Bee that can sting and lives in colonies with many other Honey Bees. Native bees can be black, yellow, red, metallic green or even black with blue polka dots! They can be fat, furry or sleek and shiny. Take the time to walk up to the Native Bee Hotel near the Rock Garden to learn more about these amazing creatures. Did you know? Native bees are vital pollinators for food plants, native plants and garden plants. Bees have five eyes and can beat their wings 200 times per second – which makes the ‘zzzzzz’ sound. Colour by number 1. Yellow 2. Black 3. Bright blue 4. Light brown 5. Bright green Native Blue-banded Bee 3 Odd lumps and bumps Plants and insects live together – sometimes in harmony, but often it’s a scuffle! Many insects rely on plants as food and for places to lay their eggs, but plants don’t always want the attention! Tiny Skeletoniser Caterpillars can chomp away on leaves just leaving the leaf veins behind. Other insects burrow into leaves and the leaf reacts by making a gall or bubble of leaf around the insect. Did you know? The little “top hats” on the heads of the Skeletoniser Caterpillars are actually the head capsules left over Sugary lerps feeding from the leaf veins from when the caterpillar moults as it grows. While the body moults are shed, for some reason this species of caterpillar hangs onto its head capsules, creating a very stylish hat! 4 Try this! As you walk around the Gardens, see if you can spot any of these strange galls or other signs of insects or animals in the bush. Once you start looking, you will spot clues everywhere! moth pupa witches’ broom gall galls cuckoo spit cicada shell 5 Fabulous feathers Feathers are remarkable things that only birds have! You can identify which birds are in an area by the feathers that you find. Can you match the feathers on the sign to the birds hiding in the trees? Hint, try to spot a Gang-gang Cockatoo, Powerful Owl, Sulphur-Crested Cockatoo and a Yellow-tailed Black Cockatoo. Different types of feathers Contour feather Semi-plume Flight feather Down Did you know? In 1970 astronaut David Scott took a Peregrine Falcon feather to the moon to demonstrate Galileo’s famous hammer/feather drop experiment. When the hammer and feather were dropped simultaneously, they hit the surface of the moon at the same time. The feather is still up there! 6 Try this! You can use feathers to make an old fashioned pen called a quill. Find a contour feather then follow the instructions. You will need help from an adult! Diagonal cut cut Step 1: Choose a contour or flight feather that feels good in your hand Step 2: Cut away the bottom barbs on the shaft Step 3: Ask for help to cut the quill using the diagrams as a guide Slit Step 4: You can now dip your pen into for ink flow food dye or diluted ink and write away! 7 Birds and flowers working together Can you spin and match each of the honeyeaters into the correct order? Honeyeaters are some of the many different birds that live in or visit the Gardens. These birds love the flowers of the family Proteaceae, which includes hakeas, banksias and grevilleas. Proteaceae flowers are often in reds, oranges, pinks and yellows, the colours best seen by birds. Did you know? Honeyeaters have beaks and tongues adapted to drink the sweet nectar buried in the base of the flowers. When they drink, pollen brushes onto their heads, which they carry to the next flower they visit, resulting in pollination – so both birds and plants benefit! 8 Master weavers Bushes and trees provide excellent places for birds to roost and nest. Some birds protect their young from predators by building their nests in dense trees or shrubs and watching over them, sounding an alarm if predators get too near! This is a nest of a Grey Shrike Thrush, one of the best songsters in the Australian bush. Their eggs are creamy white with brown and grey speckles. Can you draw a clutch of eggs in the nest? 9 Which nest is best? The Spotted Pardalote digs a burrow into sand or soil and makes its nest at the end in a little chamber. Because it is so dark down in the burrow, pardalote chicks have special glow-in-the-dark patches at the sides of their mouths to help parents guide food in! All Australian robins, including this Eastern Yellow Robin, create cup‑shaped nests in the smaller branches of trees and shrubs. To make a cup-shaped nest, birds first make a pile of raw materials, placing soft feathers or grasses on the top. They then sit in the nest and turn around and around until they form a nice firm cup. Try This! Can you find two birds in the Gardens that create a nest by building a huge mound? Hint – there is one in the Mallee Garden near the Visitor Centre and one in the Rainforest. 10 The Superb Fairy Wren creates delightful nests in grassy undergrowth. Fairy Wrens are co-operative breeders, which means that related birds remain in the territory to help the dominant pair protect and feed their young. The nest is a cosy dome made of grass, moss, rootlets, twigs and spider webs. The White-winged Chough makes mud nests on horizontal branches. These remarkable nests are made in several layers, the lower layers needing to dry before others can be added on top. They can take many months to complete. Sometimes choughs substitute animal dung for mud if mud is scarce! Did you know? Fairy Wrens in the Gardens have been studied by researchers from the Australian National University for many years. If you see birds with tiny bands around their legs it means they are being studied by scientists. There are about 50 Fairy Wren family groups living in the Gardens. 11 Extraordinary echidnas Echidnas are unusual creatures that live all across Australia. Their scientific name is Tachyglossus aculeatus. Tachyglossus means “quick tongue” as echidnas can speedily flick their long sticky tongue to catch food, and aculeatus means spiny referring to the sharp spines all over their body that protects the animals from predators like foxes and goannas. Did you know? The Echidna and Platypus are the only mammals in the world that lay eggs. These special mammals are called monotremes. The echidna’s egg has a soft shell and is only the size of a large marble. Echidnas don’t have teeth! They have rough bumps in their mouth for grinding up their favourite food of ants and termites. Try this! Help this hungry echidna find the path to the plump delicious termites. 12 Life in leaf litter Mulch and leaf litter on the soil surface provides moist dark habitats for invertebrates to live in. These tiny creatures help to break down the leaf litter, making nutrient-rich compost. Look at these wonderful compost creators! Colour them in and give each of them a name. 13 An eye-catching display Male Satin Bower-birds build bowers to impress the females. Male bower-birds attract attention by displaying blue objects around the bower, and by dancing and calling to the females. Did you know? The bower is not a nest. The female builds a nest away from the male’s bower to lay the eggs in and does all the work in bringing up her babies! The inner walls of the bower are painted daily with a paint made from chewed-up lichen and charcoal, using a chewed leaf as a brush. During a display, males bulge their eyes, arch their neck, hold their wings in incredible positions, show off prized treasures and make buzzing and clicking sounds as well – what a show! Draw in some more blue treasures around the bower in the picture. Have a good look at the colours of the male and female birds and colour them in to match. Don’t forget their purple eyes! 14 Spectacular Scribbles A tiny moth lays her eggs between the old and new bark of some eucalyptus trees. The egg hatches and the caterpillar, or larva burrows between the bark chomping away and growing bigger and fatter. This creates tunnels that get larger as the larva grows. The larva pupates in a cocoon and emerges as another tiny moth who will lay her eggs between the layers of bark on a gum tree. When the old bark falls away from the tree the scribbles left by the tunnels are revealed.

  • Beak and Feather Disease Viru
    Fact sheet Beak and feather disease virus (BFDV) is the causative agent of psittacine beak and feather disease (PBFD), an endemic disease in Australia’s wild parrot populations. Descriptions of parrots with feather loss consistent with the disease date back to the late 1800s (Ashby 1907). The virus is believed to have originated in Australia sometime following the separation of the continent from Gondwanaland, with spread to other parts of the world with modern movement of parrots as pet and aviary species . It has the potential to impact on several endangered Australian and non-Australian parrot populations and is listed as a key threatening process by the Australian government. Of late, the virus also has been identified in various non-psittacine species . Beak and feather disease virus is a 14 to 16 nm non-enveloped icosahedral DNA virus belonging to the family Circoviridae. Formerly, it was believed that the circoviruses recovered from a diverse range of psittacines were all antigenically similar. Doubt was cast on this theory when a virus that appeared to be serologically and genetically different was isolated from cockatiels (Nymphicus hollandicus) (Shearer et al. 2008). More recent research appears to indicate that psittacine circoviruses can be divided into two species and multiple viral strains. Based on work by Varsani et al. (2011), BFDV contains 14 strains, while budgerigar circovirus (BCV), a newly defined species to date only found in budgerigars (Melopsittacus undulates), contains three strains. However, it is likely that this number will continue to increase as shown by the discovery of two new distinct BFDV lineages in orange-bellied parrots (Neophema chrysogaster) (Peters et al.

  • Spring Bird Surveys in the Gloucester Tops
    Gloucester Tops bird surveys The Whistler 13 (2019): 26-34 Spring bird surveys in the Gloucester Tops Alan Stuart1 and Mike Newman2 181 Queens Road, New Lambton, NSW 2305, Australia [email protected] 272 Axiom Way, Acton Park, Tasmania 7021, Australia [email protected] Received 14 March 2019; accepted 11 May 2019; published on-line 15 July 2019 Spring surveys between 2010 and 2017 in the Gloucester Tops in New South Wales recorded 92 bird species. The bird assemblages in three altitude zones were characterised and the Reporting Rates for individual species were compared. Five species (Rufous Scrub-bird Atrichornis rufescens, Red-browed Treecreeper Climacteris erythrops, Crescent Honeyeater Phylidonyris pyrrhopterus, Olive Whistler Pachycephala olivacea and Flame Robin Petroica phoenicea) were more likely to be recorded at high altitude. The Sulphur-crested Cockatoo Cacatua galerita, Brown Cuckoo-Dove Macropygia phasianella and Wonga Pigeon Leucosarcia melanoleuca were less likely to be recorded at high altitude. All these differences were statistically significant. Two species, Paradise Riflebird Lophorina paradiseus and Bell Miner Manorina melanophrys, were more likely to be recorded at mid-altitude than at high altitude, and had no low-altitude records. The differences were statistically significant. Many of the 78 species found at low altitude were infrequently or never recorded at higher altitudes and for 18 species, the differences warrant further investigation. There was only one record of the Regent Bowerbird Sericulus chrysocephalus and evidence is provided that this species may have become uncommon in the area. The populations of Green Catbird Ailuroedus crassirostris, Australian Logrunner Orthonyx temminckii and Pale-yellow Robin Tregellasia capito may also have declined.

  • The Role of Habitat Variability and Interactions Around Nesting Cavities in Shaping Urban Bird Communities
    The role of habitat variability and interactions around nesting cavities in shaping urban bird communities Andrew Munro Rogers BSc, MSc Photo: A. Rogers A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2018 School of Biological Sciences Andrew Rogers PhD Thesis Thesis Abstract Inter-specific interactions around resources, such as nesting sites, are an important factor by which invasive species impact native communities. As resource availability varies across different environments, competition for resources and invasive species impacts around those resources change. In urban environments, changes in habitat structure and the addition of introduced species has led to significant changes in species composition and abundance, but the extent to which such changes have altered competition over resources is not well understood. Australia’s cities are relatively recent, many of them located in coastal and biodiversity-rich areas, where conservation efforts have the opportunity to benefit many species. Australia hosts a very large diversity of cavity-nesting species, across multiple families of birds and mammals. Of particular interest are cavity-breeding species that have been significantly impacted by the loss of available nesting resources in large, old, hollow- bearing trees. Cavity-breeding species have also been impacted by the addition of cavity- breeding invasive species, increasing the competition for the remaining nesting sites. The results of this additional competition have not been quantified in most cavity breeding communities in Australia. Our understanding of the importance of inter-specific interactions in shaping the outcomes of urbanization and invasion remains very limited across Australian communities. This has led to significant gaps in the understanding of the drivers of inter- specific interactions and how such interactions shape resource use in highly modified environments.

  • Spring Bird Communities of a High-Altitude Area of the Gloucester Tops, New South Wales
    Australian Field Ornithology 2018, 35, 21–29 http://dx.doi.org/10.20938/afo35021029 Spring bird communities of a high-altitude area of the Gloucester Tops, New South Wales Alan Stuart1 and Mike Newman2 181 Queens Road, New Lambton NSW 2305, Australia. Email: [email protected] 272 Axiom Way, Acton Park TAS 7021, Australia. Email: [email protected] Abstract. Annual spring surveys between 2010 and 2016 in a 5000-ha area in the Gloucester Tops in New South Wales recorded 71 bird species. All the study area was at altitudes >1100 m. The monitoring program was carried out with involvement of a team of volunteers, who regularly surveyed 21 1-km transects, for a total of 289 surveys. The study area was within the Barrington Tops and Gloucester Tops Key Biodiversity Area (KBA). The trigger species for the KBA listing was the Rufous Scrub-bird Atrichornis rufescens, which was found to have a widespread distribution in the study area, with an average Reporting Rate (RR) of 56.5%. Another species cited in the KBA nomination, the Flame Robin Petroica phoenicea, had an average RR of 12.6% but with considerable annual variation. Although the Flame Robin had a widespread distribution, one-third of all records came from just two of the 21 survey transects. Thirty-seven bird species had RRs >4% in the study area and were distributed across many transects. Of these, 20 species were relatively common, with RRs >20%, and they occurred in all or nearly all of the survey transects. Introduction shrubs such as Banksia species (Binns 1995).

  • Cumulative Learnings and Conservation Implications of a Long-Term Study of the Endangered Carnaby's Cockatoo
    Cumulative learnings and conservation implications of a long-term study of the endangered Carnaby’s Cockatoo Calyptorhynchus latirostris Denis A. Saunders1 and Rick Dawson2 1CSIRO Land & Water, GPO Box 1700, Canberra ACT 2601, Australia; Phone +61 2 6255 1016; Email [email protected] (corresponding author) 2Department of Parks and Wildlife, Locked Bag 104, Bentley DC, WA 6983, Australia; Email: [email protected] The endangered Western Australian endemic Carnaby’s Cockatoo Calyptorhynchus latirostris was studied by Denis Saunders from 1968 to 1996, and by Rick Dawson and Denis Saunders from 2009 to 2016. One breeding population at Coomallo Creek in the northern wheatbelt of Western Australia was studied intensively from 1969 to 1976, and then monitored in early September and November most breeding seasons until 1996. Monitoring resumed in 2009 following the same protocols used from 1977 until 1996, but with at least one extra monitoring visit, usually in January. This long-term research project has: confirmed that what was known as the White-tailed Black Cockatoo C. baudinii is two species, Baudin’s Cockatoo C. baudinii in the forested southwest, and Carnaby’s Cockatoo in the wheatbelt, and overlapping the range of Baudin’s Cockatoo; demonstrated photographic techniques for identifying banded individuals; proved identification of individuals based on contact calls, and suggested using individual vocal recognition as a method of non-invasive monitoring of endangered bird species; demonstrated the loss of large hollow- bearing trees was greater than replacements were being established; revealed the high rate of loss of hollows in trees still alive; shown that lack of nesting hollows may be limiting breeding; demonstrated the efficacy of artificial hollows; established methods for establishing the timing of egg-laying based on measurements of eggs, and aging of nestlings; developed a method for assessing nestling condition based on body mass; and shown that total rainfall in the first half of autumn is a significant factor in timing of egg-laying.

  • Red-Tailed Black Cockatoos Only in South-Western Australia, Are Sometimes Placed in the Genus Zanda
    Discovered by Mark Harvey, WA Museum have a confession to make – I love Australia’s black cockatoos. Whenever I I see them careen and roll above me, I get a frisson of joy. They seem to move effortlessly on gently pounding wings, calling to other members of their flock in sonorous delight. Their feeding can quickly produce a carpet of discarded gum nuts and other debris that have been torn apart in search of tiny seeds that they ingest. It’s not often that I become lyrical about nature, but these birds are wonderful and I feel privileged to witness their antics. Apart from the very different palm cockatoo, the five species of black cockatoos are placed in the genus Calyptorhynchus, but three species, the yellow-tailed black cockatoo in eastern Australia and two others, Baudin’s cockatoo and Carnaby’s cockatoo, which occur Red-tailed black cockatoos only in south-western Australia, are sometimes placed in the genus Zanda.
